l WIETHOD OF AND HARRY L. MAYNARD, OF PORTS- COATING SHIPS BOTTO MS OROTHER OBJECTS,

SPEGIFIGATION forming part of Letters 1? Application filed September 12,1902 atent No. 716,678, dated December 23, 1902.

. Serial No. 123,163. (No specimens.)

To all whom, it may concern:

Be it known that I, ALONZO P. CUTHRIELL, a citizen of the United States,residing at Portsmouth, in the county of Norfolk and 5 State ofVirginia, have invented new and useful Improvements in Methods ofCoating Ships Bottoms or other Objects, of which the following is aspecification.

This invention relates to certain new and to useful improvements inmethod ofcoating ships bottoms or other objects. I

The invention aims to provide a method particularly adapted for paintingships bottoms to prevent the corroding and fouling thereof. he method iscarried out as follows: The

obj then covered with an anticorrosive composition consisting of d ryl'grgygn fem ig gg ig eleven pounds; dry 02d of zinc, four pounds; shel- 2olag varnish, eight gallons; ra w li i s e e d pil, two andonefourthgallonsptggpentine, ode gallon; oi], o f pip e-tar,. one and offs-halfgallons. This composition is suitably combined in substantially theproportions specified. After the object has been covered with theanticorrosive composition the latter is allowed to become thoroughlydried, and it is then coated by an antifouli ing of dry bright Venetianred, ten and onefourth pounds; shellac varnish, four and one fourthgallons; raw linseed-oil, three and onehalf pints; red precipitate ofmercury, three pounds; arsmiiddsac'idfofie" punter-T he ingredientsforming the antifouling composition are suit-ably combined in theproportions substantially as specified.

The ships bottom when coated by the foregoing method will not corrodeand will be prevented from having marine bodies adhere 4o thereto.

It is thought the method herein set many advantages of the forth forpainting ships bottoms or other objects to prevent the same fromcorroding and from fouling can be readily understood from the foregoingdescripng com position consisttion, and it will also be evident that thespecified proportions of the ingredients forming the anticorrosive orantifouling composition can be changed without departing from thegeneral spirit of the invention, which consists in suitably coating theobject first with an antioorrosive composition comprising substantiallythe ingredients set forth and then coating it with an antifoulingcomposition comprising the ingredients substantially as setforth.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A method of coating ships bottoms and eat to be coated is suitablycleaned and7other objects consisting of applying an anticorrosivecomposition thereto consisting of ferric oXid, oxid of zinc, shellacvarnish, linseed-oil, turpentine and oil of pine-tar, drying the saidcoating, and then applying acoating of an antifouling composition.

2. A method of coating shipsbottoms which consists in applying ananticorrosive compo-- siti'on thereto, thoroughly drying the same, andthen applying to the said anticorrosive coating an antifoulingcomposition consisting of Venetian red, shellac varnish, linseed-oil,red precipitate of mercury,and arsenious acid.

3. A method of coating ships bottoms which consists in applying ananticorrosive composition thereto consisting of ferric oxid, oxid ofzinc, varnish, linseed-oil, turpentine and oil of pine-tar, thoroughlydrying said composition and then applying an antifouling compositionconsisting of Venetian red, varnish, linseed-oil, red precipitate of'mercury, and arsenious acid.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
